1. Some antihistamines, especially those causing sedation, might increase the side effects of amlodipine like dizziness or drowsiness.
2. Non-sedative antihistamines are generally safer with amlodipine, but sedating types can amplify amlodipine’s blood pressure-lowering effect.
3. Avoid sedating antihistamines like diphenhydramine with amlodipine, as they can enhance dizziness and lethargy.
4. There’s no strong interaction between amlodipine and non-drowsy antihistamines, but cautious use is advised with those causing sedation.
